Maryland asbestos regulations.
Who licenses asbestos work in Maryland, who takes the notification, and how long before the job you have to file. Plus how the federal rules layer on top.
State licensing & accreditation
Asbestos abatement work in Maryland is licensed/accredited through the Maryland Dept. of the Environment (MDE), Air & Radiation Administration under COMAR 26.11.21 (contractor licensing); COMAR 26.11.23 (accreditation).
Credentials the state issues:

Maryland Dept. of the Environment (MDE), Air & Radiation Administration — asbestos licensing.
Notification
Notifications go to the Maryland Dept. of the Environment (MDE) under COMAR 26.11.21; NESHAP 40 CFR 61, Subpart M.
- Advance notice: At least 10 working days in advance.
- Notification details / form.
How the federal rules layer in
No matter the state, federal OSHA 29 CFR 1926.1101 (asbestos in construction), EPA NESHAP (40 CFR 61, Subpart M), and AHERA worker accreditation still apply. A state program layers its own licensing and notification on top of — not instead of — these. Where Maryland has no state license, the federal accreditation and NESHAP notification requirements are the floor.
